NeX [460]

Answer:

Number of Model A press = 9 and Number of Model B press = 5

Step-by-step explanation:

Number of books Model A can print per day = 70

Number of books Model B can print per day = 55

Let x be the number of Model A press and y be that of Model B press.

Total number of printing presses = 14

x + y = 14 ----------------1

Total number of books printed per day = 905

70x + 55y = 905-------2

Putting y = 14 - x in equation 2, we get:

70x + 55(14 - x) = 905

15x = 135

x = 9

y = 14 - 9 = 5

Hence number of Model A press is 9 and that of Model B press is 5.

Answer:

hello your question lacks the required statements here are the statements

A spinner is divided into four sections of equal size, numbered 1, 2, 3, and 4. You spin it three times, and get 1, 4, and 3. Which statement is FALSE?

A. The theoretical probability of a 1 is 25%.

B. The experimental probability of a 1 is 25%.

C. If you spin the same spinner again and get different results, the experimental probabilities are different, but the theoretical probabilities have not changed.

D. The experimental probability of a 2 is 0%.

Answer : The experimental probability of a 1 is 25% ( B )

Step-by-step explanation:

The first statement is true because since the spinner is divided into 4 sections the theoretical probabilty is equal for all sections i.e 25% each

The second statement is false because after spinning the spinner three times ( experimental ) the results obtained were 1,4,3 hence the experimental probability of 1 would be 33.3%

the theoretical probabilities remains unchanged but the experimental probabilty can change

the experimental probabilty of 2 is 0% because after the 3 experiments the number 2 did not show up

NISA [10]

Answer:

Building is 56.58 feet long.

Step-by-step explanation:

Consider the provided information.

An aerial photograph from a U-2 spy plane is taken of a building suspected of housing nuclear warheads.

When the photograph is taken, the angle of elevation of the sun is 30°.

By comparing the shadow cast by the building in question to the shadows of other objects of known size in the photograph, scientists determine that the shadow of the building in question is 98 feet long.

As we know: $\tan\theta=\frac{opp}{adj}$
